Ofev may cause several side effects. Here are some frequently asked questions about the drug’s side effects and their answers.

Do the 100-mg and 150-mg strengths of Ofev cause different side effects?

No, these strengths aren’t expected to cause different side effects. However, your risk of side effects may increase if you take a higher dosage. This is because when you have more of a drug in your body, your risk of side effects can increase.

So, if you take the 150-milligram (mg) capsules of Ofev, it’s possible to have an increased risk of side effects than if you took the 100-mg capsules. The severity of these side effects may also be greater.

To learn more about your risk of side effects with Ofev, talk with your doctor.

However, it’s possible to experience jaundice due to liver problems, a side effect of Ofev. This can cause yellowing of the whites of your eyes. If you notice changes in the whites of your eyes during your Ofev treatment, tell your doctor. They can check for liver problems using a liver function test.

In addition, if you notice any eye problems or vision changes during your treatment with Ofev, tell your doctor. They can help determine what may be causing your symptoms and the best way to treat them.

Should I expect to develop a skin rash during Ofev treatment?

It’s possible to develop a skin rash from taking Ofev. However, rash was not a side effect that people taking Ofev reported in clinical trials. Instead, rash was reported as a side effect after Ofev became available for use. However, it’s not known for sure if rash was related to Ofev treatment.

Also, it’s possible to develop a rash as a symptom of an allergic reaction* from Ofev. If you develop a rash while taking this medication, talk with your doctor. They can help determine what may be causing your rash and the best way to treat it. If your rash is related to an allergic reaction, your doctor may have you stop Ofev. And they may recommend a different medication to treat your condition.

* To learn more about allergic reaction, see the “Side effect specifics” section above.

Be sure to talk with your doctor about your health history before you take Ofev. This drug may not be the right treatment for you if you have certain medical conditions or other factors that affect your health. These are considered drug-condition or drug-factor interactions. The conditions and factors to consider include:

Liver problems. If you have any liver problems, tell your doctor before starting treatment with Ofev. This drug can increase levels of certain liver enzymes,* which can lead to or indicate liver damage. If you already have liver problems, taking Ofev may worsen your condition. In some cases, your doctor may recommend that you take a lower dose of Ofev. However, if you have a more severe liver condition, your doctor may recommend a different treatment option for you.

Heart problems. Tell your doctor if you have any heart conditions before starting treatment with Ofev. This drug may increase the risk of blood clots,* which can cause serious problems such as heart attack or stroke. If you already have heart problems, you may have an increased risk of developing heart attack or stroke while taking Ofev. Your doctor can help determine if Ofev is a safe treatment option for you.

History of blood clots. If you’ve ever had a blood clot, including a heart attack or stroke, tell your doctor before starting Ofev. This drug can increase your risk of blood clots. If you’ve had a blood clot in the past, your risk of having one during Ofev treatment may be higher than someone who has never had one. In this case, your doctor can help determine if Ofev is safe for you to take.

Bleeding problem or family history of bleeding problems. Ofev may increase the risk of bleeding as a side effect.* If you have a bleeding problem such as anemia or hemophilia, taking Ofev may increase your risk of bleeding further. This risk is also higher if you have a family history of bleeding problems. In these cases, your doctor will help determine if Ofev is a safe treatment option for you.

Allergic reaction. If you’ve had an allergic reaction† to Ofev or any of its ingredients, your doctor will likely not prescribe Ofev. Ask your doctor what other medications may be better options for you.

Smoking. Tell your doctor if you smoke before you start treatment with Ofev. Smoking may make Ofev less effective than usual. In addition, smoking can also increase your risk of side effects from the drug. This includes blood clots, which can lead to heart attack or stroke. Smoking can also cause lung damage. And since Ofev is used to treat lung conditions, smoking during treatment may worsen your condition. Due to these risks, your doctor will likely recommend that you avoid smoking during your treatment with Ofev.

Recent surgery in your abdomen. Tell your doctor if you’ve had a recent surgery in your abdomen. Ofev may increase your risk of gastrointestinal perforation.† If you’ve had a recent abdominal surgery, you may have an increased risk of this side effect occurring. In this case, your doctor can help determine if Ofev is a safe treatment option for you.

Kidney problems. Ofev may cause protein in your urine* as a side effect. This can indicate kidney problems. So, if you have existing kidney problems, taking Ofev may worsen your condition. Also, this drug wasn’t studied in people with serious kidney problems. So, it’s not known what effects the drug may have on people with these problems. If you have kidney problems, tell your doctor. They can help determine if it’s safe for you to take Ofev based on your condition.

Diverticular disease. If you have diverticular disease, tell your doctor before taking Ofev. This medication may increase your risk of developing a gastrointestinal perforation. If you have diverticular disease, you may have an increased risk of this side effect. In this case, your doctor can help determine if taking Ofev is right for you.

Alcohol with Ofev

There aren’t any known interactions between alcohol and Ofev. However, it’s possible that drinking alcohol while taking Ofev may increase your risk of side effects from the drug. Both alcohol and Ofev may cause nausea, vomiting, or headache. So, the combination may further increase the risk and severity of these side effects.

In addition, alcohol can increase your risk of more serious side effects of Ofev.* Both alcohol and Ofev can cause liver problems. So, drinking alcohol while taking Ofev may increase this risk further.

If you’d like to drink alcohol while taking Ofev, talk with your doctor to see if it’s safe. They can advise you on how much, if any, is safe.

Pregnancy and breastfeeding while taking Ofev

Below is information about Ofev treatment during pregnancy or while breastfeeding.

Pregnancy

Ofev is not safe to take during pregnancy.

This drug has not been studied in pregnant people. So, it’s unknown what effects the drug may have on a developing fetus. However, based on animal studies and clinical trials of how Ofev works in the body, it’s believed Ofev may cause problems with fetal development.

In animal studies, congenital anomalies (also known as birth defects) and pregnancy loss were reported when pregnant animals were exposed to Ofev. However, animal studies do not always indicate what may happen in humans.

Due to these possible risks, your doctor will recommend that you take a pregnancy test before starting Ofev treatment. Also, people who can become pregnant should use effective birth control while taking Ofev. And they should use it for at least 3 months after stopping treatment.

If you are pregnant or planning to become pregnant, be sure to talk with your doctor before taking Ofev.

Breastfeeding

Ofev is not safe to take while breastfeeding.

There isn’t any information on the safety of Ofev while breastfeeding or if the drug may pass into breast milk. However, in animal studies, Ofev passes into the breast milk of animals exposed to the drug. It’s important to note that animal studies do not always indicate what may happen in humans.

However, due to the possible risks that may occur if a breastfeeding child is exposed to Ofev, your doctor will likely not recommend that you breastfeed during Ofev treatment.

If you are breastfeeding, make sure to talk with your doctor before taking Ofev.

In most cases, side effects that you may experience from Ofev are mild. However, other times, side effects from this drug may be serious.
